A comprehensive 1902 illustrated catalog of English letterpress printing and related equipment. This digital edition was scanned by Stephen O. Saxe from his copy, with additional image preparation by Dr. David M. MacMillan.
This item was scanned at 600dpi (except page 196 / PDF 208, which was scanned at 1200) and converted to JPEG images at an 85 percent "quality" setting. It has been uploaded in PDF format at two resolutions: 100 percent and (reduced in software to) 25 percent. These versions have been distinguished by encoding the percentage in the filename. If you "hover over" the "Read Online" links to the left or follow the "All Files: HTTPS" link, you will see the two sets of files. The 100 percent version (filenames starting with: "ullmer-1902-machinery-materials-sos-100pct-rgbjpg-q85") is probably better for reading online, but it is an extremely large file which may be difficult to download. The 25 percent version (filenames starting with: "ullmer-1902-25pct") should be an easier download. The "PDF" files are the original uploaded files; the "PDF with text" files are automatically derived files which are searchable but which have lower-resolution processed page images.
